Create Or Edit a Image 1

[NateBro]

I have been searching for a tutorial on how to edit a image, like a GIF or JPEG, does anyone know where i can find a tutorial that shows step by step how to create an image editor?


Thanks,

Try the image editor which is shipped with your operating system. ie Windows usually has MSPaint or an equivalent.

... What do you need to do - EDIT AN IMAGE or CREATE AN IMAGE EDITOR?

I would advise Image::Magick for the first option - and run a mile if you want to do the second!

If you're considering doing this in Perl, I'd be of the opinion to think again. I'm not saying it can't be done, just that there would be better languages suited to the task is all.

You could use Image::Magick to modify images, eg overtype, rescale, rotate, etc etc, is this what you mean?

Sorry for the confusion, but I need to Create an image editor. I know its a big project, and one of the things my company is doing is programming things in PERL, to show that it is powerful enough. we are currently working on a PERL forum, that people said we could not do it in PERL, but had to use ASP, but its all in PERL and looking great, should be done by the end of the year.



Thanks,

OK, a few pointers

get a team together
define your interfaces, GUI's, script engines
learn about file formats, and there's quite a few and some are propietary, so there could be patent infringement issues
design your GUI, with your end users in mind, not what the developer thinks is cool
implement as many image manipulation algorithms as you can get your hands on, and a few you come up with yourself
get a good book on HCI (Human Computer interaction), learn about tranformations, clipping, etc etc
decide on how you're going to handle your colour palette (or how many different ways you're going to handle it)
How many tools (brushes, erasers, smudgers, airbrushes) are you going to have, and what sort of control will the user have over them?
Are you going to handle vectors, or just rasters?
Layers?
Colour adjustments
Brightness
Contrast
Animation? again vector or raster


That should be enough to keep you going till say 5:30 ;-)

I would refer your boss to this thread before the project gets too deep

Well Paul's off to a good start - I think everyone here is trying to politely point out that this is an outrageous undertaking. I've been using Perl for years and i wouldn't even know where to start. And just take a look - as Paul states - at the number of file formats. This would probably make the most hardened computer programmer cry. I seriously doubt they realise what they are asking you to do. I honestly can't think of anything more difficult.

duncdude, I honestly can't think of anything more difficult.

I am kinda scared now, but I think thats the reason they want it done.

Sit down, work out a plan, ask your boss for the budget and resources required, and he'll tell you then it's no longer a requirement

I wouldn't worry about the speed, the hardware nowadays will look after a lot of that

Budget point 1. Server dual proc €20K
Budget Point 2. Project Manager (3/12 Months) €50K
Budget Point 3. Programmers x 3 (dunno rates for programmers any more)
Budget Point 4. Test Suite $$$
Budget Point 5. Analyst ($70-150K pa)
Budget Point 6. Documentation x 2 ($$)
Budget Point 7. Morale building parties $$$$
....


That's a bit flippant, but you get an idea of the scale involved

HTH

Ok, My Boss i's going to take a look, at this.

Hmm I know you say the h/w will take care of it - but I still think it *might* be a bit slow.

You cannot really appreciate Dilbert unless you've read it in the
original Klingon.

Want great answers to your Tek-Tips questions? Have a look at faq219-2884

 

[MikeLacey]

Oh and your costing for a project manager is a bit low...

3 outta 12 months, and I'm told some of them are on 200K over there. I don't care I'm not taking a pay cut for anyone ;-)

Thanks guys so much, still in the research for this project, but i will let you know the out come.

Good to hear from you

I've recently become aware that "the GIMP" is actually an image editor built in gTk/Perl

I'd start by looking at the GIMP ...
